CIGARETTE-MACHINE.

SPECIFICATION forming part of Letters Patent No. 294,113, dated February26, 1884.

Application filed January 23, 1883. (No model) To all who/1t zit mayconcern:

Be it known that we, JAMES BURNS, of

Brooklyn, in the county of Kings and Stateof New York, and ALEXANDERBUOKMAN, of 5 Schodack Depot, in the county of Rensselaer and State ofNew York, have invented certain new and useful Improvements inCigare't'teMachines, of which the following is a specification.

Our invention relates to improvements on the cigarette-machine for whichLetters Pat ent No. 259,090 of the United States were granted to us onthe 6th day of June, 1882; and the object of our present improvements isto remedy certain defects in the operation of the machine above referredto, and to adapt it to operate so that rice-paper and other tender andfragile wrapping materials may be used for the wrapping of thecigarettes made by it, the said wrapping materials being, by reason oftheir inherent weaknesses, unable to withstand the strain necessarilyexerted by the feeding mechanism employed in our earlier machine, andthe use of that class of wrapping materials being considered essentialto the production of the best class of goods renders our presentimprovements a necessity.

A further object of our improvements is to effect, by means of aretrorse arrangement of the pins in the periphery of the-tobacco-feedingwheel, a more thorough compaction of the tobacco in the cigarette-stock,and a more per feet removal of the particles of tobacco from said pins.

In the accompanying drawings, which form part of this specification, andto which reference is made herein, Figure l is a side elevation of therear part of our improved cigarette-machine; Fig. 2, a plan View ofsame; 40 Fig. 3, an enlarged side view of portions of the tobacco-feeding wheel, feeding-table, tongue-pieces, and grooved wheel, and thecombined stripping and compressing device, and folding mechanisms; Fig.4, a longitudinal section of Fig. 3,- Fig. 5, aplanview of Fig. 3, withthe tobacco-feeding wheel removed for the purpose of exposing underlyingparts; Fig; 6, alike view, showing the arrangement viewed in thedirection indicated by the arrow marked thereon; Fig. 12, an invertedplan view of the first folder; Fig. 18, a detached detail, showing ourimproved arrangement for adjusting and securing the bed containing thepasting device; and Fig. 14, a rear elevation of the arrangement ofpulleys and gearing for 6 5 imparting the requisite motions to theseveral parts of the machine.

As represented in the drawings, A designates the bed-piece of themachine, which is provided with a raised plate or platform, a, wheretothe several parts of the wrapper-folding mechanisms are attached; B, thetobaccofeeding wheel; 0, a large grooved wheel for maintaining thewrapper in a proper troughshaped form during the operation of fillingand for feeding forward the cigarette-stock to the folding and finishingmechanisms; D, the feeding-table; E, the feeding channel-piece; F, thepasting device G, an endless belt, which serves as an auxiliary feedingmechanism for the cigarette-stock, and H the recip- 'roeating head forthe cuttingtoff mechanism.

The bed-piece A may be made in the form shown or in any other suitableform. A platform, a, is secured to said bed-pieceand ar- 8 ranged at aproper height therefrom to suit the requirements of the several partssecured to said platform, as hereinafter explained.

The grooved wheel 0 is secured to a shaft, 0, which is adapted to rotatein hangers 0, secured to the under side of the bed-piece A. The saidwheel is provided with a peripheral groove, 0, whose width coincideswith the diameter of the continuous cigarette-stock to be formedtherein. The upper part of said wheel 5 is projected through the upperface of the plat? form a, so as to bring the bottom of the groove 0 on atrue line with the upper faces of the tongue-pieces I and J, which aresecured up on the upper face of the platform a at opposite sides of theaxial center-line of the wheel 0. Said tongue-pieces are respectivelyprovided with tongues i and j, which are fitted into the groove 0, so asto form at the upper side of the wheel 0 tangents to the bottom of thesaid groove, and produce substantially a straight continuous surfacewith the bottom of the groove 6-.

The tongue-piece I, which is fixed behind the center line of the wheel0, is provided at each edge with checks 2 which correspond in height andthickness to the standin flanges which form the sides of the groove 0'in said wheel. The said checks are fitted to the curvature of theperiphery of the wheel 0, and they form, behind the line of the axialcenter of said wheel, a short stationary groove, i, which corresponds insize and position to the groove 0" in said wheel. At their rear ends theupper edges of the cheeks t have an up ward inclination, as at i, andthelateral space between them is increased at the same point, as shownin Fig. 6, for the purpose of forming an outward]y-expanding throat,v'i. The up ward and lateral inclinations thus given to the checks '6give to the strip of wrapping material its initial, bends, so as to forma trough of said, wrapper preparatory to its receiving its filling oftobacco.

The tongue-piece J is fixed in front of the line of the axial center ofthe wheel 0, and is made and fitted to said wheel in the mannerdescribed for the tongue-piece I, excepting that it is unprovided withany checks.

The tobacco-feeding wheel B is adapted to rotate in the directionindicated by the arrow marked thereon.

Said wheel is provided with two peripheral rows of projecting pins, Z),which, instead of being radial, as shown in our former patenthereinbefore referred to,

are curved or inclined backward in respect to the direction of themovement of said wheel, and this backward inclination is given to saidpins for the purpose of obtaining a more effective action of them inpressing the tobacco into the trough form of wrapper as it lies in thegroove 0 and if, and for effecting a more perfect removal of the shredsof tobacco from said pins by means of the stripping device hereinafterdescribed. In front of the wheel 13 a brush, 1), is arranged to bearagainst the periphery of said wheel, so as to remove therefrom and fromthe pins b all shreds and particles of tobacco adhering thereto,which(shreds and particles) will then drop into the receptacle b, from whencethey can be readily removed. An outwardly-inclined guard-plate, If, isprovided with an elastic edge of rubber, b, which bears against theouter face of the feeding-wheel B, to deflect and prevent all dust ordirt from falling upon the pasted edge of the wrapper.

The wrapper, cut in a continuous strip of at width suited totherequircdsize of the cigar- 1 ette, is rolled upon a reel, M, which rotates instandards fixed upon a movable bed, m, at the rearmost end of themachine. The bed m is provided 011 its under side with outwardlytlaringanglepieces in, against which the two oppositely located adjustingscrews W are adapted to bear insuch manner that they will adjustthe said bed and its attached. reel M sidewise, and at the same timesecure them in place on the machine.

The pasting device consists of a pastingdisk, F, which, for the purposeof applying the paste in closely-adjacent spots, we pref erably makewith a serrated edge. Said disk is revolved by means of the moving stripof wrapping material in a trough, f, containing paste or other suitableadhesive material. A

.disk, is secured to the same spindle, but is placed outside of thetrough f, and affords the required support to the unpasted edge of thestrip of wrapping material as the latter is fed forward over the pastingdevice. The said pasting device is fixed upon a movable bed, ,1,provided on its under side with divergent angle-pieces f, which receivethe pressure from two oppositely-located adjlisting-screws, f", for thedouble purpose of laterally adjusting the pasting device and securing itin place on the machine.

The feeding-table D forms an extension to the feeding channel-piece E.The latter is arranged at the under side of the after part of thefeeding-wheel B in such manner that the periphery of said wheel willextend into the channel 6 of said channel-piece. Said channel 0 is madeof sufficient depth to leave considerable clearance therein beyond theends of the pins 1) of the feeding-wheel, so as to insure the certaintyof an ample supply of tobacco being carried by the pins 13 through saidchannel, for effecting the proper filling of the cigarette-stock. Thechannel 0 has its bottom curved so as to maintain a uniform distancefrom the periphery of the feeding wheel B, and to permit the tobacco tobe moved therethrough without producing any compression of the fiberswhile in said channel. The lower part of the channel-piece E is providedwith a tongue, 0, (through the front end of which the channel cis cutdown in such manner that sufficient space will be left between thebottom and sides of said tongue and the adjacent parts of the throat i"to permit the wrapping material to pass therethrough. i i

Underneath the forward portion of the feeding-wheel B there is fixed acombined stripping and compressing device, K, which is fit ted toconform to the periphery of said wheel, and is provided withlongitudinal slots k, so formed that the pins I) will pass through them;but any tobacco borne upon said pins will be stripped therefrom by theunder edge of the roller, f, of the same diameter as the pastingto thelower edge of said tongue,) which is insorted into the throat i" of thetongue-piece I v wardly over the tail it.

piece K and deposited in the trough form of wrapper lying in the groove0 The under face of the stripper K is placed at a slight inclinationlengthwise iii-respect to the bottom of the groove 0 as formed by thetonguesz' and j, and is so adjusted that the forward end of its tail It"will lie at a height from the bottom of the said groove that willcorrespond to the thickness of the finished cigarette-stock. Theinclination given, as above described, to

the under face of the stripper K serves to still further compress thefilling of tobacco contained in the trough of wrapper in the groove 0before the edges of said wrapper are folded over and adhered together.The upper part of the stripper K, where it comes in contact with theperiphery of the wheel B, has its central part cut away to form achamber or recess, as shown in Fig. 10, wherein any loose dust or fineparticles of tobacco that may be carried through the'slots k by the pinsI) can fall and lie harmless. The cutting away of said central partreduces the rubbing-surface of the walls composing the slots 70, so thatwhen said walls or the pins 1) become gummed by the juices from thetobacco they will pre sent less resistance to the passage of said pinsthrough the slots 70 than they would if said walls were maintainedthrough the entire depth of the stripper. The forward edge of saidstripper is cutaway-at both sides to form a' throat, k, as shown in Fig.9, for facilitating the operations of the folding mechanisms. From saidthroat the tail k is graduated in depth through its longitudinal centerline, but retains a uniform width of face 011 its under side until itterminates in a thin edge at its forward end. A folder, L, by means ofwhich the pasted edge of the wrapper is turned over as thecigarette-stock is fed forward, overlaps the tail k of the stripper froma point near the throat k", where the space between said tail and folderis greatest, as shown in Fig. 10, until it'reaches the front end of thetail k,

where the spring end Z of said folder bears upon the pasted spots on thewrapper andv l the cigarette-stock is fed forward, folds over the upperor unpaste'd edge of the wrapper, to cover the pasted and turned-downedge, and the two edges are pressed, together, first, by the crown ofthe groove Z in the folder L, and then by the rounded face of thepressing-wheel Z, whereby the two flaps are caused to adhere in aperfect manner to each other.

The auxiliary feeding mechanism, consist ing of an endless belt, G,carried on pulleys g,

and the grooved holding-bar g is fully described in our Patent No.259,090, hereinbefore referred to, and therefore a further descriptionof it is unnecessary.

The mechanism for cutting the cigarettestock into the required lengthsfor use consists of a horizontally-reciprocating head, H, which carriesa vertical]y-reciprocating knife,

71 that is operated in substantially the same the separated cigarette upto the plane of the head H into a position where it will receive apressure from the outcoming cigarette-stock in such manner that thesevered cigarettes will be successively pushed from the head H into anyproper receptacle placed at the forward end of the machine to receivethem.

The driving-shaft 2, which imparts motion to all the movable parts ofthe 1nachine,is provided on its farther end with a pulley, 3, forreceiving a driving-belt, by which the said driving-shaft is rotated. Asecond pulley, 4, is also fixed on the same end of the drivingshaft, andfrom this latter pulley a crossed belt conveys motion through a pulley,5, to the tobacco-feeding wheel B. On the opposite end of thedrivingshaft 2 a crank-wheel, 6, is

secured for the purpose of imparting motion to the reciprocatingheadH,in the manner described in our former Patent No. 259,090. A removablepinion, 7, is attached to the driving-shaft 2 (near its farther end) andgears into an idle pinion, 8, (shown in dotted lines in Fig. 14) whichrevolves on a stud, 9, that is adjustable in the curved slot 10, (alsoshown in dotted lines in Fig. 14.) The said idle pinion gears into thewheel 11 secured to the shaft 12 on which the first pulley g of theauxiliary feeding mechamism is also secured. Provision is made by meansof the curved slot 10, whose curvature is parallel to the periphery ofthe wheel 11, to substitute pinions of different sizes in the place ofthe pinion 7, so as to vary the relative speed of the shaft 12 and itsdependent parts in respect to the speed of the drivingshaft 2. Aremovable pinion, 13, is fixed on the shaft 12 to gear into anidlewheel, l4,whicl1 latter gears into the wheel 15 secured to the shaft0, which carries the grooved wheel 0. The wheel 14 rotates on a fixedstud, 16, which is adjustable in the curved slot 17 of the pendentbracket 18, (shown in dotted lines inFig. 1.) The slot 17 has acurvature that is parallel to the periphery of the wheel 15, so'that thewheel 14 can be raised I and lowered as occasion requires, and thewheels 14 and 15 will be properly retained in gear with each otherwhenever such changes are made. By reason of the adjustability of thestud 16 in the curved slot 17 pinions of I wheel B, while said wrapperis receiving its different sizes may be substituted in place of fillingof tobacco, and it will also be observed pinion 13, so as to change theperipheral speed of the wheel 0 in respect to the speed of the endlessbelt G, to properly adjust the move ment of them as occasion mayrequire.

The operation of our improved machine is as follows: The roll ofwrapper, out to the required width in a continuous strip, is placed onthe reel M at the rear end of the machine, as shown in Fig. 1. Fromthence the wrapper is carried over the pasting device in such mannerthat the under side of the nearest edge will bear upon the upper edge ofthe pasting-disk F to receive its proper application of the adherentmaterial. From the past ing-disk the wrapper passes beneath the guideroller N, and thence into the space between the tongue 6 and throat r,wherein said wrapper receives its initial folding to form a trough. forreceiving its filling of tobacco. The said trough form then passes intothe channel-way formed by grooves o and tfland as it emerges from underthe tongue 6 it receives its first charge of tobacco fromv thefeeding-wheel B at a point where (as will be seen by referring to Fig.4) the space in the groove 2' beneath said feeding-wheel has itsgreatest depth. By the rotations of the feeding-wheel Bits pins b aresuccessively brought into position to engage in the loose tobacco whichlies on the table'D in the path of said pins, and by the latter thetobacco will be carried through the channel 6 and deposited in thetrough of wrapper lying.

in the groove't' The surplus depth of the channel 6 and the clingingnature of the to bacco-fibers both conduce to the delivery of asufficient quantity of tobacco, in a slightly compressed condition, intothe trough of wrapper lying in the groove in advance of the channel c,and the compaction of the tobacco is augmented by the action of the pins1), whose retrorse arrangement enables them to continue to exert apacking pressure against the filling in the wrapper until the points ofsaid pins pass entirely above the under side of the stripper K. As fastas the filling in and compacting of the tobacco into the trough ofwrapper is effected, the partially-formed cigarettestock is fed forwardby the grooved wheel 0, and as the said stock moves forward the pastededge of the wrapper is turned over by the folder L, as hereinbeforedescribed, and the upper or unpasted edge of said wrapper is turned overby means of the folder L upon the pasted and turned-down edge, and thetwo parts are further pressed together and caused to adhere by means ofthe rounded face of the pressing-wheel Z The latter operation completesthe formation of the cigarette-stock, which then consists of acontinuous bar, of uniform size, of compressed tobacco enveloped in acontinuous wrapper. It will be observed that the two edges of thewrapper are maintained in erect positions at the opposite sides of thegrooves c and f, so as to form an open trough of the wrapper beneath thefeedingthat this trough form of the wrapper is maintained by the unitedaction of the tongue 6, the lower part of the wheel 13, and the afterpart of the stripper K, until said wrapper has received its filling andis brought into the folder L. As fast as the cigarette-stock iscompleted, it passes out from beneath the pressing-wheel 1 onto theendless belt G, and is guided forward bythe grooved holding-bar 9' intothe cutting-off mechanism heretofore described,whereby thecigarette-stock will be separated into the lengths required by theadjustment of the feeding mechanisms.
